Hat + nhc98 version 1.08
========================
We are pleased to announce a new release of Hat and the nhc98 compiler.
This is a stable release, containing many bugfixes in both the compiler
and the Hat tracing and debugging tools. If you have not yet tried out
the Hat tracing system, this is a good opportunity to give it a workout.
New features of note in release 1.08 are:
* There are "tunnels" between hat-observe, hat-detect, and hat-trail,
enabling the user to jump directly from one view to another at
exactly the point of interest.
* You can now have multiple copies of hat-trail running simultaneously.
* The nhc98 compiler implements the recent revisions of the
Haskell'98 Report.
nhc98 is a full compiler for Haskell'98, with extensive support for
space profiling, time profiling, and tracing your programs.
The system is available as source code, which can be built with the
Gnu C compiler on any 32-bit platform, or with any already-installed
Haskell compiler. Binary packages are also currently available for
ix86-Linux and sparc-solaris2.
